    "abstract": "The evanescent coupling from a photonic crystal resonator to a micron-thick\noptical fiber is investigated in detail by using a 3D-FDTD method. Properly\ndesigned photonic crystal cavity and taper structures are proposed, and optimal\noperating conditions are found to enhance the coupling strength while\nsuppressing other cavity losses including the coupling to the slab propagating\nmode and to the higher-order fiber mode. In simulation, the coupling into the\nfundamental fiber mode is discriminated from other cavity losses by spatial and\nparity filtering of the FDTD results. The coupling efficiency of more than 80%\ninto the fundamental fiber mode together with a total Q factor of 5,200 is\nachieved for the fiber diameter of 1.0 um and the air gap of 200 nm between the\nfiber and the cavity.",
